Actually what you see/experience is correct. If you think about it in the real 3d world… you have a 2 sided poster, with images on both sides. If you slice them up into columns and rotate each individual columns 180 degrees, the “back” image will look like as if each column would positioned in the “wrong” way – even though they are correct.
To accomplish what you want to do correctly, use the Card Wipe transition effect, not Card Dance.
